I'm going to say this all ethnic groups do it in their music... People just tend to Rap and R&B cause they do it the most, let's take a trip back to the 90's when heavy metal and grudge rock was popular acts like Marilyn Mansion and Nirvana (which is my fave) talk about suicide, rape and even have outrageous things going on while on tour... The school shoting incident in 98 was influenced by rock music so if u going to point fingers point it at everyone
